Repression of the LEAFY COTYLEDON 1/B3 regulatory network in plant embryo development by VP1/ABSCISIC ACID INSENSITIVE 3-LIKE B3 genes.
Article in Plant physiology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 137 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plant embryo development is regulated by a network of transcription factors that include LEAFY COTYLEDON 1 (LEC1), LEC1-LIKE (L1L), and B3 domain factors, LEAFY COTYLEDON 2 (LEC2), FUSCA3 (FUS3), and ABSCISIC ACID INSENSITIVE 3 (ABI3) of Arabidopsis (Arabidopsis thaliana). Interactions of these genes result in temporal progression of overlapping B3 gene expression culminating in maturation and desiccation of the seed. Three VP1/ABI3-LIKE (VAL) genes encode B3 proteins that include plant homeodomain-like and CW domains associated with chromatin factors. Whereas val monogenic mutants have phenotypes similar to wild type, val1 val2 double-mutant seedlings form no leaves and develop embryo-like proliferations in root and apical meristem regions. In a val1 background, val2 and val3 condition a dominant variegated leaf phenotype revealing a VAL function in vegetative development. Reminiscent of the pickle (pkl) mutant, inhibition of gibberellin biosynthesis during germination induces embryonic phenotypes in val1 seedlings. Consistent with the embryonic seedling phenotype, LEC1, L1L, ABI3, and FUS3 are up-regulated in val1 val2 seedlings in association with a global shift in gene expression to a profile resembling late-torpedo-stage embryogenesis. Hence, VAL factors function as global repressors of the LEC1/B3 gene system. The consensus binding site of the ABI3/FUS3/LEC2 B3 DNA-binding domain (Sph/RY) is strongly enriched in the promoters and first introns of VAL-repressed genes, including the early acting LEC1 and L1L genes. We suggest that VAL targets Sph/RY-containing genes in the network for chromatin-mediated repression in conjunction with the PKL-related CHD3 chromatin-remodeling factors.
